Removing the RAID controller
Attention: Do not open your server or attempt any repair before reading and understanding the “Safety information”
on page iii and “Guidelines” on page 19.
This section provides instructions on how to remove the RAID controller if your server has one installed.
Notes:
1. Use any documentation that comes with the RAID controller and follow those instructions in addition to
the instructions in this section.
2. Your RAID controller might look slightly different from the illustration in this section.
3. When you disconnect the power source from the server, you lose the ability to view the LEDs because
the LEDs are not lit when the power source is removed. Before you disconnect the power source, make
a note of which LEDs are lit, including the LEDs that are lit on the front control panel.
The RAID controller is installed on the riser card assembly. To remove the RAID controller, do the following:
1. Remove all media from the drives and turn off all attached devices and the server. Then, disconnect all
power cords from electrical outlets and disconnect all cables that are connected to the server.

the cables from the RAID controller.

card assembly.

card assembly” on page 36.
